GEORGE BAYER, OF NEW YORK, N. Y.

LOCK.

SPECIFICATION forming part of Letters Patent No. 242,864fdated June 14, 1881,

' Application filed September 16, 1880. (Model) To all whom it may concern Be it known that I, GEORGE BAYER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Locks, of which the following is a specification.

The object of this invention is to produce a lock having the least possible Width, for use upon the doors and drawers or other parts of furniture; and to this end it consists in a sliding tumbler constructed with parallel slots and with a key-opening and a bolt-opening, which are arranged in a substantially rectilinear plane entirely within the edges of the tumbler, in combination with fixed guide-pins engaging the slots, a sliding bolt constructed with a nib or projection engaging the bolt, and a key-arbor projecting into and through the key-opening, as hereinafter more fully set forth.

This invention is illustrated in the accompanyin g drawings, in which Figure 1 repre- Fig.2 is Fig. 3 is a like view taken beneath the tumbler.

Similar letters indicate corresponding parts.

The letter A designates the sliding tumbler; cl d, the slots; f, the key-opening, and l the bolt-opening thereof.

B designates the sliding bolt, and O the lock-case inclosing the tumbler and bolt.

The slots d d are parallel to each other, and are arranged at or near the opposite ends of the tumbler, while the openings f Z are located intermediate of the slots, in a rectilinear plane therewith and with each other, the whole being entirely within or between the edges of the tumbler, as clearly shown. c e designate the guide-pins engaging the parallel 'slots cl cl, these pins projectinginward from the back of the lock-case O.

The bolt B moves at a right angle to the tumbler A on a stump, h, fitted into a slot, 2', therein, this stump being a fixture of the lockcase.

i k designates the nib or projection of the bolt engaging the bolt-opening Z. This opening l is shaped with a contraction between its ends, through which the nib 7c passes when the bolt is shot or retracted.

g designates the key-arbor projecting into the key-opening f from the back of the lockcase. This arbor receives the barrel of a key, N, the bit of which is so shaped that when the key is turned it actuates both the tumbler A and the bolt B to shoot or retract the latter, as the case may be, one part of the bit impinging against the edge of the opening fand the other part passing behind the tumbler to catch in the usual notch of the bolt.

It will be seen that by the arrangement of the slots 01 d and the openings f l in a substantially rectilinear plane within the edges of the tumbler the width of the lock can be reduced to a minimum, leaving the tumbler at operating with guide-pins, nor to construct it with a key-opening within the edges thereof, and I do not claim such, broadly; but

What I claim as new, and desire to secure by Letters Patent, is

Theimproved drawer-lock herein shown and described, the same consisting of the tumbler provided with end slots, 61 d, the key-opening .f, and the bolt-opening l, with the lock-case having the guide-pins, key-arbor, and lockingbolt provided with the nib k, all constructed and arranged as and for the purpose set forth.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
